A systematic review and data synthesis will be carried out of randomized controlled trials of BP for the treatment of patients with SP and ARDS. RevMan 5.3 software will be used for statistical analysis.
Results: This systematic review will evaluate the efficacy and safety of BP for the treatment of patients with SP and ARDS. The primary outcome includes respiratory indexes, blood biochemical and inflammatory factors. The secondary outcomes consist of complications, sepsis, abdominal hemorrhage, renal failure, length of hospital stay, and mortality.
Conclusion: This study will provide up-to-date evidence of BP for the treatment of patients with SP and ARDS.
